Display devices of the kind above eferred to are useful for informatory, promotional and entertainment puroses. p it is a broad object of the invention to provide a novel imoroved display device of the general kind above referred to in which the message appearing in the Window of the device is gradually changed in a surorising and concealed manner.

A specific object of the invention is to provide a novel and improved display device in which pliable strips bearin the pictorial representations or other messages alternately visible in the window of the device are guide and held taut by a floating slide whereby transition from one pictorial representation to the other can be effected in a smooth, simple concealed manner by sliding an actuating member of the device from one limit position to another one.

Another specific object of the invention is to provide a novel and improved display device of the general kind above referred to in which manipulation of the device successively exhibits different sets of printed information which may be associated with the pictorial representations, or independent therefrom.

It is also a specific object of the invention to provide a novel and improved display device which can be conveniently and inexpensively manufactured in that all of the components of the device consist of blanks which may be stamped out of paper or other suitable material and can be joined by folding and gluing operations.

Other and further objects, features and advantages of the invention will be pointed out hereinafter and set fonth in the appended claims constituting part of the application.

in the accompanying drawing several embodiments of the invention are shown by way of illustration and not by Way of limitation.

In the drawing:

EIG. l is an elevational front view of the device showing one message fully visible in the window of the device.

FIG. 2 is a view similar to FIG. 1 showing the transition from one message to another.

FIG. 3 is a view similar to FIG. 1 and showing the second message fully visible in the Window.

FIG. 4- is an ei view of the device.

FIG. 5 is gserspective detail view of ly cut-ogcn unfolded FIG. 6 is a view similar to FIG. 5 but slowing the components of the device in a different operational condition.

device in part- 7 shows stops mean for limiting the movement of the operating sli e of the device to v e position shown in FIG. 3.

FIG. 8 is an elevational front view of a modification of the display device,

9 shows the device of FIG. 8 in a different operahe f Patented Aug. 16, 1%65 the envelope which is visible in FIGS. 1, 2 and 3 includes a window 15 of any suitable configuration, a window having a generally rectangular shape being shown. A slide 5%? also made of strong paper, thin cardboard or other suitable material is slidable into and out of the envelope. Displacement of the slide in reference to the envelope causes one of two messages to be visible in the window. The two messages are symbolized by letters A. and B. In practice the messages may and usually will consist of two pictorial representations which may be of informatory, promotional or entertaining nature. The messages may also co isist of appropriate printed data. Generally speaking, there is no limitation on the nature of the message, provided only that it can be made visible in window 15. It is also not necessary that the entire message be visible in the window at one time. Successive parts of a message may be exhibited in the window as the slide is displaced.

FIG. 1 shows o aerating slide 55 pushed fully into envelope 1d and the message A is exhibited.

PEG. 2 shows the slide partly pulled out and in a position in which the message A is disappearing and the second .iessage represented by letter B is beginning to appear.

PEG. 3 shows the slide fully pulled out and the entire messge B is now visible in the Window.

n of slide from the position of 3 into the position of FIG. 1 causes the message B to disappear gradually and the message A to appear gradually until finally the message A is again fully visible.

The manner in which the transition from one message to another in a concealed manner is effected by manipulation of slide will now be described in detail in connection with FIGS. 4 through 7.

Referring to FIG. 4 which shows the display device in exploded form, envelope ill comprises a face sheet 11 and a. back sheet 32 joined along a fold line 13. Face sheet ill is formed with a bottom flap l6 folded over and glued to back sheet i2 along a strip 1?, preferably so that the bad sheet 12 is on the outside of the flap. Flap 1'7 is cut at through part of its width and the cut upper porof the flap is bent back and glued against the inside of flap to to form a double layer at the inside of the flap. This double layer constitutes a stop edge 19 for .a purpose which Will be more fully explained hereinafter. Face sheet 11 is further formed with an end flap upon which is glued back sheet 12 along a strip 21. As it is now apparent, envelope constitutes a pocket closed at three sides but open along its edge 11a when the face sheet and the back sheet are glued together as described. Finger grip recesses 25 and 25a are provi ed in the face sheet and the back sheet. These two recesses are in registry when the envelope is glued as can be clearly seen for instance in Fl -d5. l, 2 and 3.

The operating slide 59 is also of rectangular con figuration, the general dimensions of the slide being such that the same can be accommodated in the envelope, as 18 shown in l. The slide cut out along one of its longitudinal edges to form a shoulder 27' c-oacting with stop shoulder i? in a manner and for a purpose which will be explained hereinafter.

I The opposite lengthwise side of the slide may also be set ofi at 28 so that the portion of the slide pulled out or" the envelope as shown in FIGS. 2 and 3 is of uniform Width.

The display device further comprises two pliable strips and 31. The two strips may be made of a suitable smooth, thin and adequately strong paper, but they may also be made or" a fabric. End Ella of strip 34) is secured to the inside of face sheet 11 at 32, preferably by gluing and the other end 36'!) of strip 3% is secured to slide 5d at 33, preferably also by gluing. Similarly, one end 33a of strip 33 is secured to the inside of face sheet 11 at 3 referably by gluing and the other end 311) of strip 31 is secured to slide 563 at 35, preferably by gluing. To

facilitateattachment. of strip end 311) to slide 50 without subjecting the strip to wear due to engagement with flap 20, slide 50 is cut out at 36 and the strip end 31b is folded over the cut-out portion 36.

. The two strips are'bearing the aforedescribed messages symbolized by letters A and B. As it is apparent, window 15 is'placed somewhat out of center in the exemplified embodiment. To compensate for such displacement of the window, strip 30 is somewhat longer than strip 31.

The display device finally comprises a guide slide 40. This slide which may be made of a paper of sufficient rigidity or also of thin plastic has a slot 41 extending transverse of the direction of movement of operating slide 50, as shown in FIGS. 1, 2 and 3 and is of a length sufficient to accommodate strips 30 and 31. The two strips extend through slots 41 in a manner best shown in FIGS. and 6. As it is apparent, the two fold lines thus formed in the strips are located within slot 41 and each strip will straddle the respective lengthwise edge of slot 41. The lengths of the strips and the points of attachment thereof are so correlated that guide slide 49 will hold taut the strips at all times and guide the same when passing through the slot.

- As it is apparent, the fold lines of the two strips are separated in the slot by a gap depending upon the width of the slot. This separating gap will be visible when and while slide 40, or more specifically the slot thereof is exposed in window 15. To conceal the gap and with it the separation between the two strips, a cover strip 66) is provided. The strip is attached to guide slide 40 on the side thereof adjacent to the inside of face sheet 11. The attachment of the cover strip to slide 40 is such that the two strips can pass between cover strip 60 and the respective side of slide 40 into and through slot 411 thus concealing the separation between strips 30 and 31.

a Cover strip 60 may be secured to guide slide 4-9 in any suitable manner. It has been found advantageous to provide an upper tongue 61 and a lower tongue 62 on the cover strip. These two tongues are bent over the respective edges of guide slide 40 which is formed with recesses 49a and 40b to accommodate the tongues as it is clearly shown in FIGS. 5 and 6. The tongues are shown to be lengthwise elongated to form smooth guide surfaces for message strips 30 and 31 as the same move along guide slide 40. The tongues further serve the purpose of reinforcing the guide slide at the portions at which it is most weakened by slot 41. As may be observed, there are three thicknesses, namely the thickness of the guide slide propen'the thickness of the shield portion 60a of strip 60 and the thickness of tongues 61 and 62 respectively.

FIGS. 5 and 6 show guide slide 46 straddled by message strips 30 and 31 and the cover strip 66 attached to the slide. The figures also show all the components of the device in their functional positions, though it should be understood that in FIGS. 5 and 6 the components are still somewhat pulled apart to show more clearly the coaction of the components.

FIG. 7 and also FIGS. 1, 2 and 3 show the fully assembled display device.

The operation of the display device as hereinbefore described is as follows:

The position of operating slide 50 as shown in FIG. 5 corresponds to the position of the slide in FIG. 1, that is the slide is completely pushed into envelope 10 and letter A is exposed in window 15. When the slide is now pulled out, that is pulled from the position of FIG. 5 into the position of FIG- 6 which corresponds to FIG. 3, sldie 55) will pull the portion of strip 30 located between slide 561 and guide slide 40 outwardly, thereby gradually increas-' ing this strip portion in length and correspondingly decreasing the length of the portion of strip 30 located between guideslide 40 and the face sheet 11 and secured to the latter. Similarly the length of the portion of strip 31 located between face sheet 11 and guide slide 40 increases and the length of the portion of strip 31 located between guide slide 44 and back sheet 12 decreases. Due to these changes in the lengths of the strips, portions on opposite sides of guide slide 4%), the guide slide is compelled to move toward the open side 11a of the envelope when and while slide 50 is being pulled out and to move in the opposite direction when the slide is pushed in. The dislacement of the guide slide in either direction causes continuously changing portions of one or the other strip to be exposed in the window and also the gap between the two strips to travel past the window. However, the gap is concealed by the shielding or cover strip 6% as previously described. Accordingly, a person observing the window will first see one message in the window. This message will appear to be gradually wiped out by strip portion 6% traveling across the same and to be gradually replaced by appearing portions of the second message. Accordingly, there are intermediate stages, one of which is indicated in FIG. 2 in which both messages are partly exposed in the window (see FIG. 3). The opposite operations takes place when the slide is pushed in.

As is clearly shown in FIGS. 5, 6 and 7, the outward movement of slide 59 is limited by engagement of shoulder 2'7 with stop edge 19. The stop means may be ar ranged in various ways, for instance a tongue may be bent out of the lefthand edge of face sheet 11, or a piece of material may be glued to the face sheet or the back sheet in the appropriate position.

According to FIGS. 8 and 9, the movement of slide 50 is utilized to exhibitadditional messages. To this end a second window "it? is provided in'face sheet 11 and/or the back sheet. Intelligence indicated at 71 is printed or otherwise provided on siide 54) or on strip 30; and such additional information will appear section by section when and while the slide is pulled out or pushed in. The message printed on the slide or the strip may be suppiemented by data appearing on the outer side of the face sheet or the back sheet adjacent to window '70. The additional information exposed in window 7%) may be associated with the messages exposed'in window 15 or may be independent therefrom. For instance, the messages exposed in window 15 may be in the form of technical components and the information appearing in window 7 0 may contain data pertinent to the technical components, or other data of interest While the invention has been described in detail with respect to certain now preferred examples and embodiments of the invention, it will be understood by those skilled in the art after understanding the invention, that various changes and modifications may be made without departing from the spirit and scope of the invention, and it is intended therefore to cover all such changes and modifications in the appended claims.
